A tool for replacing a coupler knuckle of a coupler of a railway wagons comprises a base trolley, a rotating hand wheel, transmission gears, lifting double-screw bolts and coupler knuckle fixtures, wherein the transmission gears are three gears, which are completely as same as each other, engaged with each other and mounted on a platform of the base trolley; the rotating hand wheel is mounted on one transmission gear; the two lifting double-screw bolts are arranged on the other two transmission gears and can rotate with the transmission gears; and the coupler knuckle fixtures are mounted on the lifting double-screw bolts and can be used for clamping a knuckle at the front end of the coupler knuckle of the coupler. The tool for replacing the coupler knuckle of the coupler of the railway wagons, provided by the invention, has the advantages of simple structure, low cost, safety, high efficiency and convenience in use. As the motion of the rotating hand wheel is converted into the motion for stably lifting the coupler knuckle of the coupler upwards, the force for lifting the coupler knuckle upwards is reduced and the part is very stably moved to a desired height. Meanwhile, as the platform of the tool is both an operation platform in the operation of personnel and a tool for transporting materials by using railway tracks, the wagons are convenient to overhaul.
